On LED Dimming and LED Lighting Energy Saving Benefit

With the weather climate change so drastically in recent years, all inhabitants on the Earth face a severe Energy Saving battle! While LED Lighting has been accepted for its energy saving benefit, it’s counter-intuitive to learn that end-users often find the LED lights are much brighter than necessary, which becomes another form of energy wastage!

In the last few years, Legend Tech is glad to be able to play our role in driving LED dimming applications. By assisting our customers completing their dimming projects, we’ve developed our market understanding and strengthened our product design to meet the market requirements.

In 2015, we launched our 450W/220-240Vac LED Phase Dimmer and a 2.1A Type-A USB Power Adapter (DZ1G2.1USB) to local market under the DIMEZE™ brand name. DZ2G450DIAL is our Gen 2 LED Dimmer with a rotary button interface and it only requires a single Live-wire from the AC Mains to provide a phase-cut output (chopped sine-wave) to subsequent LED dimmable fixtures. DZ1G450CAPS is our Gen 1 LED Dimmer Switch with a push button interface, which has integrated Light On/Off and Dimming functionalities to a single push button.

In 2016, we launched our Low Voltage DC 1-10V Controller to cover 0/1-10V Dimming applications. DZ1G1TEN is our 1-10V controller with Minimum-Trim option; the Minimum-Trim option allows the installer to set the lowest brightness level corresponding to 0.8 – 3.5V. Besides our own product development, we realized collaboration with our associated LED Lighting manufacturers is another critical element of market success. We began to explore Product Compatibility with other Dimmable LED Driver Manufacturers. Since then, the support from other manufacturers has helped us winning a good number of successful projects for our DZ1G1TEN with Mean Well and few other manufacturers’ 0/1-10V dimmable drivers.

In 2017, we launched our Gen 3 LED Phase Dimmer, DZ3G450DIAL, as an enhancement of our DZ2G450DIAL for wider LED dimmable product compatibility. The Minimum-Brightness set button is re-located making it easier for practical use. Furthermore, we managed to get the DZ3G450DIAL officially recognized by SORAA® as a compatible dimmer for its standard LED lamps. Since there is little information on how to select LED Dimmable Drivers to match a LED Lighting Fixture, based on our field experience, we’ve compiled the relevant info into our Application Notes.

In 2018, we launched our Gen 4 LED Phase Dimmer, DZ4G450MULT, as further enhancement of our DZ3G450DIAL core. This device has an additional Two-Way Dimming functionality, which is typically not achievable with single pole light dimmer. We also began to explore other dimming products, such as On-Cord dimmer. After learnt from some customers about their bad experience of catching a fire with using TRIAC-based on-cord dimmer for table lamp applications, we’ve specially implemented an Overheat Protection feature to our on-cord dimmer design, which gives ourDZ1G200LINE.
